Levítico 10

afin que vous puissiez distinguer ce qui est saint de ce qui est profane, ce qui est impur de ce qui est pur,

Y para poder discernir entre lo santo y lo profano, y entre lo inmundo y lo limpio;

And that ye may put difference between holy and unholy, and between unclean and clean;

You are to make a distinction between the holy and the common, and between the unclean and the clean.
